 # Retrospective
 
+*"The only real mistake is the one from which we learn nothing."*
+*— Henry Ford*
+
 ## Stop Doing
 
+- **Lack of Active Participation:** Due to some personal issues, some team members
+  were less active, which slowed down progress. In the future, we need
+  to ensure clearer communication regarding availability and constraints.
+
+- **Underestimating the Importance of the Project Board:** We didn’t fully
+  recognize the value of using the GitHub project board at the start. This resulted
+  in some miscommunication as some members had to ask about which solutions need
+  to be reviewed.
+
 ## Continue Doing
 
+- **Collaboration and Flexibility**: When some members struggled in dealing with
+  GitHub and Python, others where there to help which ensured successful
+  submission of solutions and reviews in time. Also, when some members didn’t
+  find solutions to review, others implemented additional solution to provide
+  challenges for teammates to review. **We should continue such actions to help
+  our success in the Certificate program.**
+- **Regular code reviews using GitHub:** Now since we have seen how better it
+  is to communicate about the code through Github,
+  all of us are focusing on developing this skill for better code management.
+- **Regular Check-ins:** Having meetings helped us stay connected and
+  clear on progress, despite some delays.
+
 ## Start Doing
 
+- **Deadlines, deadlines, deadlines**: We should've set clear deadlines for each
+  task. This would've ensured early successful submission of the project and
+  we will have enough to fix any last-minute errors/problems.
+- **Organized Project Board and Label Usage:** We need to use the GitHub project
+  board more efficiently. This would ensure effective communication and delivery.
+  Also, we need to write more about the code in the description of the PR/issue.
+  This is something we didn't stick to in this project as the solutions were simple.
+- **Clearer Role Definition:** It’s important that to define individual roles
+  and responsibilities more clearly from the first meeting. This will ensure
+  each member understands their specific contributions.
+- **Capabilities Discussion**: We have to discuss our capabilities of using the tools
+  that will be used in detail, not just saying "I'm beginner". This would help
+  making it clear from the beginning which members will need help the most.
+
 ## Lessons Learned
 
+- **Collaboration, collaboration, collaboration:** Team members in any project
+  should be effectively collaborating with each other. Besides ensuring successful
+  delivery of the project, such communication will ensure that no members do more
+  than they have to.
